Wilks Calculator

The Wilks Calculator returns points using original Wilks or the revised March 2020 protocol. Enter a confirmed total, or add your best squat, bench press and deadlift. Bodyweight and lift units are selected separately.

Interpreting Wilks points

Wilks points combine a confirmed lifted total with a bodyweight-adjustment coefficient. Enter the total directly or add the best squat, bench press and deadlift. The three-lift mode adds actual recorded performances; it does not infer maximum lifts from repetition sets. Select the men’s or women’s coefficient basis and record bodyweight and lifting units independently. The score describes the selected mathematical protocol. It is not a population percentile, training prescription or an eligibility decision.

Confirmed performance

Use recorded lifts or a recorded total, rather than a repetition-max prediction.

Named protocol

Keep the coefficient basis and any source clamp attached to the reported points.

Wilks worked example

The men’s preset uses 90 bodyweight and a 500 confirmed total. It returns ≈ 319.20 on the original Wilks basis. Its coefficient is approximately 0.638394076, multiplied by the confirmed total in kilograms.

The women’s preset uses 60 bodyweight and a 350 total. It returns ≈ 461.66 with the March 2020 revised protocol. The three-lift preset adds 200 squat, 125 bench press and 225 deadlift. Its total is 550 and its score is ≈ 351.12 . Values displayed as approximate are rounded; the engine retains unrounded points.

Coefficient limits and weight units

This calculator converts entered masses to kilograms, then follows the cited OpenPowerlifting implementation’s explicit bodyweight bounds before calculating its coefficient. Original Wilks uses 40–201.9 for the men’s coefficients and 26.51–154.53 for the women’s coefficients. The March 2020 revision uses 40–200.95 and 40–150.95 respectively. Entered weights outside those source bounds are accepted within the tool’s input capacity, but the coefficient uses the nearest source boundary. Both entered and adjusted weights remain visible.

One international avoirdupois pound is exactly 0.45359237 under the NIST definition. Bodyweight and total can use different entered units; the calculator converts each separately. The coefficient is evaluated from the named source polynomial, and points equal the confirmed kilogram total multiplied by that coefficient. Original Wilks uses a fifth-degree polynomial and normalization 500; the March 2020 revision uses a separate fifth-degree polynomial and normalization 600. Calculation details identify the applied coefficient and source-adjusted bodyweight.

The local input capacity is bodyweight from 0.01 through 1000, with individual lifts and the combined total from zero through 10000, measured in the selected lifting unit. Numeric entries accept at most 64 characters and 20 decimal places and must retain their canonical decimal value. These parser limits are separate from the coefficient source bounds.

Original Wilks and Wilks2020 use different scales

The original Wilks and revised March 2020 protocols use separate coefficient systems, so their point values are not interchangeable. The original version is the default; the version control selects the primary result, and calculation details show both scales for the same entered performance. The Wilks2020 basis here is the March 9 revised implementation captured from OpenPowerlifting, rather than an unnamed early table.

A competition may select a different scoring rule. Check the rule applicable to that event before treating a calculated score as its official result. This page does not add age coefficients or apply IPF GL. For the separate fourth-degree protocol, use the DOTS Calculator. For estimates from a repetition set, use the One Rep Max Calculator.
